IMPROVEMENT IN TURBINE WATER-WHEELS.

n Hoag- The Schedule referredto in these Lettera Patent and making paxt ox' the same To all whom it may concernv Beit known that I, E. F. COOPER, of Mount Gilead,

vin the county of Morrow, and State of Ohio, have invented a new and valuable Improvement in Turbine Water-Wheels; 'and I do hereby declare that the following is a full, clear, and exact description of the ccnstruction and operation of the same, reference being "had to the annexed drawings, making'al part of this specification, and to the letters and figures of reference marked thereon.

Figure l, of the drawings, is a sect-ion of my invention through the line X X.

Figure 2 is a section of my invention taken through the line Y Y. Y

My invention relates to turbine wheels, and consists, mainly, in the construction and novel arrangement of devices, whereby eiicient and economical purposes are subserved.

'Ihe letter A, of the drawings, lrepresents the casing, cast in two parts, A and A', which aresecured together by bolts and nuts, at a a.

Bis the regulating-gate, placed in the mouth of the casing, and turning on journals b l1.

C represents the shaft of the wheel, to which the cyinder-heads D' D are firmly secured. g y l D represents the wheel thus constructed.

Cylinderhea-ds 1)' D' are formed with circular grooves in their inner surfaces, tov receive the lips formed at each end of the iron staves d d. y Q

Each bucket d is curved, so as to` present its con` cave surface to the force of ythe water. Each bucket is cast on a separate stave, 'so that when the staves are joined, to form the body of the wheel, the buckets tall into their proper places. A

The lips at each end of the staves tit into the circular grooves in the cylinder-heads, which are drawn tightlytogether, by means of bolts and nuts E E, making the wheel secure and firm.

The casing is so constructed that it allows the concussion of the water to act on about one-half of the ysurface ofthe buckets, one-quarter being covered above by a flanch, h, constructed in the upper casing, and one quarter covered below by a similar Hauch, h, in the lower casing. l

The reactionary force of the water is allowed to act on the whole concave surface 0f each bucket. After use, the water passes freely ou-t at both ends of' the It is apparent, from the construction of this wheel, that it is\ very easily packed and transported. Y

Itis a reversible wheel, being capable of either' a right-hand or left-hand movement. lhe journals of the gate may be` reversed in their bearings, and the ends of the buckets may be changed toA the opposite cylinder-heads, \vl1en,. by turning the casing upside down, what was a right-hand movement, will become a left-hand movement, and vice versc.

The cylindrical body of the wheel is made up with from six to fourteen separate staves, each having c ast on its'outer surface a bucket.

What I claim as my invention, and desire to secure by Letters Patent, is- I The rversible turbine wheel,'herein described,hav ing reversible casiugs A A', with llanches h yh and gate B, andvwheel D, having grooved cylinder-heads D' D and separate reversible buckets d d', cast on ,separate iron staves d d, all constructed and arranged to operate substantially as specified.

In testimony that I claim the above, I have hereunto subscribed my name,iu the presence of two witnesses.
